Competition between planar and central chiral control elements in nucleophilic addition to ferrocenyl imine derivatives

Competition between planar and central chiral control elements in nucleophilic addition to ferrocenyl imine derivatives

Planar chirality associated with the ferrocene in ferrocenyl oximes and hydrazones bearing chiral auxiliaries effectively competes with or overrides the normally excellent stereocontrol afforded by the auxiliary in determining the diastereoselectivity of addition to the C=N bond.
